Main Line Clog Clearing
Roots from mature trees block clay laterals, so main line backups are a frequent Granada Hills call.

Granada Hills is full of roomy 1950s and 1960s ranch homes on wide, tree-lined streets. Those mature trees and that age of plumbing make sewer lines and water heaters our most common calls here.
Plumbing in Granada Hills, in short
Granada Hills calls mostly involve root-damaged clay sewer laterals, aging water heaters, slab leaks in original copper and worn valves and fixtures in mid-century homes. We use camera inspections and leak locating to find the real cause, give typical price ranges before starting and finish most repairs in one visit.
How we cover Granada Hills
Granada Hills spreads across the north Valley from the flats near Devonshire Street up into the foothills, with the 405 and 118 freeways meeting at its east side near North Hills. Wide streets, big lots and mature trees define much of the area. The Balboa Highlands tract holds a cluster of mid-century modern homes with open plans, and some original designs carry radiant heating tubing in the slab.
The trees that shade these streets are a big reason sewer calls run high. Parkway sycamores, ficus and pines reach the clay laterals that carry waste from 1950s and 1960s homes to the street. Older homes also carry original copper in the slab, and the area felt the 1994 Northridge earthquake strongly, so some plumbing still shows hurried post-quake repairs.
Homes and pipes
Granada Hills homes and their plumbing
- 1950s and 1960s ranch homesMost homes are single-story slab houses with copper supply and clay laterals. Larger lots often have pools and long sewer runs.
- Balboa Highlands mid-century homesThese modern homes have post-and-beam framing and slab floors. Wall cavities are shallow and ceilings are often exposed, so pipe routing takes planning.
- Foothill streets on slopesHomes on the higher streets have steeper laterals and longer supply runs. Some sit on raised or stepped foundations.
- Mature parkway treesWide streets with old trees mean roots near nearly every lateral. Root intrusion is the top sewer issue here.
What people call about
Plumbing problems common in Granada Hills
Sewer Camera Inspection
Buyers and sellers here often want a camera check of the lateral before closing, since replacement costs can be high.
See the detailsWater Heater Replacement
Original heaters are long gone, but many replacements from the 2000s are now due again.
See the detailsSlab Leak Repair
Copper in the slabs of mid-century homes wears thin, and leaks show up as warm spots or a climbing water bill.
See the detailsToilet Installation
Older toilets in dated bathrooms use more water and crack at the base, and owners swap them for modern low-flow models.
See the detailsWater Heater Earthquake Strapping
Many homes still have straps from older installs that no longer meet the two-strap requirement.
See the detailsTree roots and sewer laterals in Granada Hills
Roots don't break a sound pipe. They find a joint that has opened slightly, follow the moisture inside and grow into a mat that catches paper and grease. In Granada Hills, where clay laterals are often six decades old and the trees are big, that process is ongoing on many streets.
Clearing roots with a cutter or a jetter restores flow, but roots return. Many owners clear the line once or twice a year for a while, then decide on a permanent fix. Pipe bursting or lining seals the line against roots without digging a long trench across the yard. Clearing usually runs about $250 to $600, while lateral replacement typically runs $6,000 to $16,000 depending on length and method. Those are typical ranges, not a quote.
A cleanout at the house makes all of this cheaper. Without one, we have to pull a toilet or work from the roof vent. If your home lacks one, adding a two-way cleanout pays for itself after a couple of service calls. Our article on roots in clay pipe has more detail.
Questions we hear
Questions from Granada Hills
Should I get a sewer camera inspection before buying a home in Granada Hills?
Yes, especially for homes from the 1950s and 1960s with clay laterals and big trees nearby. A camera inspection shows roots, cracks, offset joints and sags, and it gives you a recording to use in negotiations. The cost is small compared with a lateral replacement discovered after closing, when the repair is entirely yours.
Can you repair plumbing in a Balboa Highlands home in Granada Hills without harming the design?
Yes, with planning. Post-and-beam homes have exposed ceilings and shallow walls, so we look for routes through closets, cabinets and attic edges before cutting anything. Where slab lines fail, rerouting can often follow existing chases. We go over the route with you before starting so original features stay intact.
Do water heaters in Granada Hills need new straps when replaced?
Yes. Any replacement in the City of Los Angeles must meet the two-strap rule, with one strap in the upper third and one in the lower third of the tank, plus a flexible gas line and a properly routed relief valve line. We include that in every install and pull the LADBS permit. Our strap check guide shows what to look for.
